Flags of participating countries flutter in the wind at the Olympic village in Gangnueng, South Korea, Thursday, Feb. 1, 2018.  In a rare sight, North Korean flags flew in South Korea on Thursday as the South prepared for the Winter Olympics that has brought a temporary lull in tensions surrounding the North's nuclear program.  The Olympic village in Gangneung turned into a selfie site as volunteer workers posed under a North Korean flag that has been raised in the country for the first time since a hockey tournament in April last year.
